Kuberetes Dashboard version issue

[Jorge-Sasiain]

Hello,

When I was deploying the OpenNESS controller with Kubernetes-Dashboard enabled I got the following error due to failed metrics-server helm chart dependency:

2021-01-13 10:16:56,278 p=19856 u=root n=ansible | TASK [kubernetes/dashboard : download helm chart dependencies] ****************************************************************************************************************************************************************************************************************

}

STDOUT:

MSG:

Upgrading _dashboard_version: v2.0.3 to _dashboard_version: v2.1.0 in roles/kubernetes/dashboard/defaults/main.yml fixed it for me (I think v2.0.5 onwards should work), but I'm not sure if this has other implications. Here's the related issue in the Kubernetes-dashboard repository: https://github.com/kubernetes/dashboard/issues/5689, and related commit: https://github.com/kubernetes/dashboard/pull/5666/files

Hi @Jorge-Sasiain, Thanks for your feedback. Upgrading this component shouldn't impact anything in negative way. We will take a closer look at this problem and address it in future releases.
